Description:Global illumination is important for many applications such as animation, computer games, architecture, design and etc. However, the main issue in this field is the slow converging rate of algorithms. This research focus on improving the efficiency.

Description:Group motion is important for animation and game. However, the computation is time consuming. Therefore, we try to explore the possiblity of presimulating the motion of groups and then dynamically synthesize new motions from existing clips.
